Co L23-edge photoabsorption spectra of Co compounds under various pressure conditions: (a) EY-XAS of dehydrated CoCl2 powder, measured under high vacuum (1 × 10−5 Pa), (b) EY-XAS of dehydrated CoCl2 powder, measured under normal ambient-pressure conditions, (c) EY-XAS of dehydrated CoCl2 in silica gel, measured under normal ambient-pressure conditions, (d) FY-XAS of dehydrated CoCl2 in silica gel, measured under normal ambient-pressure conditions; the spectra in (c) and (d) were simultaneously observed. (e) EY-XAS of dehydrated CoO powder, measured under high vacuum as a standard material. XAS obtained by EY detection are indicated by solid lines and that by FY detection is indicated by a dashed line.
